Inter-membrane forces between archaeal-like membranes with different polar headgroups
Archaeal lipid membranes are made up of unique lipids which contain ether rather than ester linkages and branched isoprenoid hydrocarbon chains. Archaea are also known to have lipids with diverse polar headgroups but the contribution of these headgroups to bilayer structural parameters hasn't been well studied in archaea. Using neutron diffraction we can characterize how membrane structural parameters differ between archaeal lipids with different polar head groups. We propose to vary the relative humidity using the BerILL chamber to precisely increase the membrane hydration, leading to swelling of the bilayers. These swelling experiments can be then used to compare the differences in the inter-membrane forces between bilayers with different headgroup compositions.
